4 Claim.

This invention relates to a humidifier. or atomizer of the portable variety. It is an object of the invention to provide an apparatus of this character which is compact in form and still g possesses highly eflicient operating characteristics.

A further object is that f providing a humidi- -fier or atomizer whic s rugged and simple in r/ construction ch will operate quietly and efficient y over long periods of time with freedom from mechanical difficulties.

With these and" other objects in mind, reference is had to the accompanying drawings, in which- I Fig. 1 is a side elevation in cross-section of a humidifier embodying one form of the invention herein described;

Fig. 2 is a side elevation in cross-section of the rotor and pump members of said humidifier; Fig. 3 is a top view of the rotor member shown in Fig. 3; while 4 Fig. 4 is a top view partially broken away of a detail of Fig. 3, and shows the central portion of the rotor member adjacent its hub.

In the several views a container body In, oiE any suitable shape, is shown partially filled with a liquid ll. Supported in the container by means of shoulder portions I2 is a dome or cover member l3, which in turn is provided with a 0 series of vents or outlet openings II. This coyer portion is supported on the container body by spaced cushioning elements I2a. which may be made of felt or other suitable material, which in turn provide for a passageway from the outer 5 air to the interior of the container body under said shoulder portion. Extending downwardly from said dome is a l5, which additionally serves as a motor mounting. This pan is provided with drain openings IS in its lower surface and additionally supports legs II, to which are fastened a ring shaped flange III. This flangeis provided with a pluralityof vertically shaped slots I9 adjacent its lower portion and immediately above the upward extent of said slots is 4 a horizontal positioning member 20, upon which rests the electric motor 2|. This motor is formed with a rotating drive shaft 22, to which is secured, by means of a set-screw 23, a rotor or diffusing disk 24. Co-operatlng with said 50 rotor and positionedcentrally thereof is a downwardly extending hollow pump member 25, which extends beneath the surface of the liquid positioned within the bottom of the container 55 This tubular pump member. may be provided with a lower, cap portion 23, formed with a central opening 21, through which water is caused to enter as the pump is rotated, and thereafter rises in the interior of the tube to a point adjacent the openings 28 which connect with the de- 5 pressed reservoir portion 29 of. the rotor or diffusing disk. Covering this reservoir portion is a fine mesh wire guard member 30, which prevents moisture from leaving the reservoir in other than minutely, divided particles. 10

It will likewise be noted that the rotor or diffusing disk is provided with a knife edge 3| at its periphery. Current for the operation of the motor is supplied by means "of an electric cord 32, which may be interrupted, as at 33, by 5 the insertion of a switch for making and breaking the circuit.

The pump member 25 may, as shown, be enplosed in a mesh strainer 34,, which completely encircles the same and prevents clogging of the 20 pump due to the presence of foreign matter in the liquid to be atomized. This strainer is secured to the pan [5 by means of supports 35. Additionally, the under surface of the diffusing disk or rotor 24 is provided with fan blades 36 25 which may, as shown, be formed of struck-down portions of the disk itself, or, as is obvious, may be formed of independent members secured thereto. The entire structure may, for convenience, be supported on leg members 31, which 30 may be formed of rubber, felt, or any other suitable material.

' In operation, the liquid in the container body. may be scented with any desired perfume or odor, and thereafter the apparatus set into action. A rotation of the pump member 25 causes the liquid ,to rise in the interior thereof and overflow into the reservoir 29 forming a part of.

the diffusing disk or rotor 24.-Continued rotation of the parts causes the liquid in the reser- 40 voir 29 to overflow onto the upper surface of the disk and travel along the upper surface to the periphery thereof, where it leaves the disk in the form of a fine mist or spray and is dashed against the flange or ring l8 and leaves the same through the vertically extending slots l9. Thereafter the air circulated by the fan blades 36 causes the finely atomized moisture to rise upwardly through the ports or vents l4 and into the chamber to be humidified. Any products of condensation incident to this cycle are deposited in the bottom of the pan l5 and drain back into the container body through the openings l6. Circulation of air is effected by means of the spacing members In, which allow air to enter the container body under the shoulder portion of the dome and thereafter to be expelled through the openings by the actuation of the fan.

Thus, among others, the several objects of the invention as specifically aforenoted, are achieved. It will be appreciated that numerous changes in construction. and rearrangement of the parts might be resorted to without departing from the spirit of the invention as defined by the claims.

Having thus fully described the invention, what is claimed as new and desired to be protected by Letters Patent is:

1. A humidifier including in combination a container body, a support associated therewith, a motor mounted on said support with its axis in a vertical plane, a pump member coupled to said motor and extending downwardly therefrom, a disk secured to the upper end of said pump member and disposed in a horizontal plane, said disk being provided with an annular depressed ring portion adjacent its point of contact with said pump member and a passageway leading from the interior of said pump member to said ring portion, and a screen member secured to the upper surface of said disk and covering said annular ring portion thereof.

2. As an article of manufacture a diffusing disk for use in connection with a humidifier apparatus, said disk being of the type adapted for horizontal rotary mounting, being formed with a downwardly extending annular ring portion adjacent its center, and a wire mesh covering for association with the upper surface of said disk and extending beyond said annular ring portion.

3. A humidifier including, in combination, a container body, a motor positioned in said con-. tainer with an axis in a vertical plane, a pump associated with said motor and extending downwardly therefrom, a disc forming a part of said 10 pump and positioned at. the upper end thereof for rotation in a horizontal plane, said disc being provided with a reservoir portion adjacent its point of contact with said pump member, an opening communicating from said pump to said reservoir and a porous member carried by said disc in spaced relationship to the upper surface thereof, said member forming a cover for said reservoir portion.

4. As an article of manufacture, a diflusing disc for use in, a humidifying apparatus, said disc being of the type adapted for horizontal rotary mounting and being formed with a depressed reservoir section adjacent its center and a water porous member positioned on the upper face of said disc in spaced relationship thereto and extending beyond and covering said reservoir portion of said disc.
